First I've heard of it also!  It might make things a little easier
because there's not much space round there, but it isn't necessary.
Maybe it was a way to charge you for refilling (inadequately from the
sound of it) the AC.

Highly likely to be a crack at the base of the nipple on the expansion
tank.  Mine is in that state at the moment.  I presumed it was the hose
clamp not gripping tightly enough, so I tightened it, and then replaced
it and I still got some spitting.  If you wiggle the hose back and
forth, you can see the crack open and close.

New expansion tanks aren't expensive - GBP15.50 from Euro Car Parts in
the UK.  I'd replace the cap at the same time - GBP2.50.


p.s. Maybe it's time to find a new mechanic?
